Billing rules

Discounts

Three discount tiers are available based on your committed consumption amount. Discounts apply separately to request fees and resource occupation fees.

Committed consumption amount (USD)	Discount on topic or queue request fee	Discount on topic or queue resource occupation fee
[10, 800]	0.95 (5% off)	0.8 (20% off)
(800, 3,000]	0.9 (10% off)	0.6 (40% off)
(3,000, 100,000]	0.85 (15% off)	0.4 (60% off)

Note

Note: A lower value represents a larger discount. If your account already has a discount larger than the savings plan discount, the larger discount applies. The two discounts cannot be combined.

Offset rules

SMQ supports only the pay-as-you-go billing method. Fees are calculated every hour, and a bill is generated at an interval of 24 hours. After a bill is generated, the savings plan balance offsets fees first.

Offset formula:

Offset amount = Bill amount x Corresponding discount

Example 1: No existing discount

Assume you purchase a savings plan with a committed amount of USD 10,000. This falls in the (3,000, 100,000] tier, so the request fee discount is 0.85 (15% off) and the resource occupation fee discount is 0.4 (60% off).

Bill amount	Discount	Offset amount
USD 1,000 for the request fee	0.85	USD 1,000 x 0.85 = USD 850
USD 10 for the resource occupation fee	0.4	USD 10 x 0.4 = USD 4

Remaining balance in the savings plan: USD 10,000 - USD 850 - USD 4 = USD 9,146.

Example 2: Existing 25% discount

Assume your account already has a 25% discount (0.75) and you purchase a savings plan with a committed amount of USD 10,000. For each fee type, the system applies whichever discount is larger, determined by the lower value.

Bill amount	Discount applied	Offset amount
USD 1,000 for the request fee	Existing discount: 0.75 (25% off). Savings plan: 0.85 (15% off). The existing discount is larger (lower value), so 0.75 applies.	USD 1,000 x 0.75 = USD 750
USD 10 for the resource occupation fee	Savings plan: 0.4 (60% off). Existing discount: 0.75 (25% off). The savings plan discount is larger (lower value), so 0.4 applies.	USD 10 x 0.4 = USD 4

Remaining balance in the savings plan: USD 10,000 - USD 750 - USD 4 = USD 9,246.

Calculate committed consumption amount

Use the following formula to determine the appropriate committed amount before purchase:

Z = X x Discount on request fee + Y x Discount on resource occupation fee

Where:

X = estimated total request fee (USD)
Y = estimated total resource occupation fee (USD)
Z = committed consumption amount (USD)

Calculate Z for each of the three discount tiers. Select the Z value that falls within its corresponding tier interval.

Calculation example

Assume your estimated request fee is USD 1,000 and your estimated resource occupation fee is USD 10.

Committed consumption amount (USD)	Discount on topic or queue request fee	Discount on topic or queue resource occupation fee	Z value	Result
[10, 800]	0.95	0.8	Z1 = USD 1,000 x 0.95 + USD 10 x 0.8 = USD 958	Does not fall in [10, 800].
(800, 3,000]	0.9	0.6	Z2 = USD 1,000 x 0.9 + USD 10 x 0.6 = USD 906	Falls in (800, 3,000]. Select this value.
(3,000, 100,000]	0.85	0.4	Z3 = USD 1,000 x 0.85 + USD 10 x 0.4 = USD 854	Does not fall in (3,000, 100,000].

The appropriate committed consumption amount is USD 906.
